使用触觉开关重新启动Python脚本
[英]Restart Python Script using a Tactile Switch
问题描述
is it possible to manually restart a python script using a tactile switch that will be connected to the raspberry pi? 
是否可以使用将连接到树莓派的触觉开关手动重启python脚本？ I'm currently working on a thesis project that involves using a number recognition script to determine the expiration of a license card. 我目前正在从事一个论文项目，该项目涉及使用数字识别脚本来确定许可证卡的到期时间。 Thank you. 谢谢。

Yes, this would be possible using a Raspberry Pi and would likely require a thread listening for the event from the button to happen. 是的，使用Raspberry Pi可以做到这一点，并且可能需要一个线程来监听按钮中的事件以进行操作。 Then call a restart function in the python script. 然后在python脚本中调用重启函数。
Edit, found this article explaining how it can work with a library called GPIO. 编辑，找到了这篇文章，解释了它如何与称为GPIO的库一起使用。
